Yesterday I installed 12.10 in my Sony Vaio laptop. I have Huwaei E173 3G modem, I simply inserted that modem into USB slot, after a few seconds modem started blinking and activated. I opened network profile and created a new network under 'Mobile broadband' tab everything was automated and I felt awesome, infact I used net for a while.

Next morning, I placed modem into USB, but nothing happened, no sign of modem presence even the modem is not blinking, I tried creating a new connection once again but attained no luck.

The same happen to me .I was using a Huawei 3G modem. In my case i disabled networking and re-insert the modem and wait for sometime. After sometime i enabled networking and wait for few seconds. After few seconds i found the option for enabling mobile broadband. I choose the network connection profile which was listed . If you have enabled automatic connection your internet connection will started when you clicked Enable mobile broadband. Hope this works. Iam a complete newbie to Ubuntu . Just starting out few weeks before.
